Cover: Nematode-infested field plots showing 'COAN', the world's first peanut (Arachis hypogaea L.) cultivar with resistance to root-knot nematode [Meloidogyne arenaria (Neal) Chitwood]. The gene for resistance was transferred from the wild species, Arachis Cardenasii Krapov. and W.C. Gregory. At bottom, COAN seed on left and pods on right. Healthy COAN plants in two rows at upper left. Dead plants in adjacent rows are 'Tamrun 96'. Dead plants in front range are 'Florunner'. Other plots are additional nematode-resistant breeding lines.
